BACKGROUND OF THE INVENTION

1. Field of the Invention

A drift control device for use with a small boat adrift to effect thedirection and drift speed of the small boat against the forces of windand current.

2. Description of the Prior Art

Often, fishermen fish from a boat while adrift.

A boat adrift relatively close to the shore-line or river bank whilefishing will generally cause the small boat to veer into the directionof the wind commonly referred to as weather-cocking. Weather-cocking canforce the boat toward or away from the shore-line or river bank.

The degree of weathercocking depends on such various factors as windangle, the shape and profile of the small boat's hull, the small boat'sload distribution, the amount of hull side-slip which is governed bywind force and hull draft, and the depth of the water in which it isbeing operated.

Various devices have been invented to provide directional controlaccounting for the current and wind forces on a water craft. Pertinentexamples of the prior art are disclosed below.

U.S. Pat. No. 8,100,075 B2 relates to a rudder control assembly for aboat comprising a control unit having a left control plate and a rightcontrol plate; a control unit having a left connecting unit and a rightconnecting unit; a front end of the control unit being connected to theleft control plate and the right control plate; a rudder unit installedat a tail end of the boat; the rudder unit including a right shaft; arudder body; a left extension plate, a right extension plate, a drivingplate and a rudder; The right shaft is connected to the boat body androtatable axially. A lower end of the right shaft is connected to thedriving plate. The driving plate is connected to the left connectingunit and the right connecting unit. The left connecting unit and theright connecting unit are hard rods.

U.S. Pat. No. 8,210,114 B2 discloses stop member is affixed to anelongated rudder blade near its top and projects forward beyond theleading edge of the blade. A frame in which the blade is slidablelengthwise extends along a portion of the trailing edge of the blade andforward along the opposite sides. A separate mounting block has a groovereceiving a portion of the leading edge of the blade. A pivot componentis mounted in the groove for engagement against the underside of thestop when the blade is in a normal upright steering position.

U.S. Pat. No. 4,889,006 shows a kayak steering apparatus for controllingkayak weathercocking during operation in side wind conditions. Anelastomeric line in tension and a non-elastic control line are eachattached to opposite side arms of a vertically pivoting rotor which ismounted to the stern of a kayak with the rotor further being connectedto a rudder. A kayak operator can, by hand, pull on or release thecontrol line which acts in combination with tension in the elastomericline to turn the rotor and thereby set rudder angular position. Forsetting vertical depth, the rudder is connected to the rotor by a pinwhich allows the rudder to pivot about a generally horizontal axis.Depth adjustment is also hand controllable by pulling or releasing aline connected to the upper portion of the rudder at a location offsetfrom the horizontal axis defined by the pivoting pin.

U.S. Pat. No. 3,990,385 teaches a self-steering mechanism for a sailboatcomprising the combination, of a wind vane mounted for rotation about asubstantially vertical axis coupled to a differential hydraulic pressureregulator. A hydraulic motor and pump is provided having a pressureregulator located between the motor and pump. The arrangement is suchthat the hydraulic pump, which can be driven by movement of the vesselthrough the water, the wind or other suitable sources, provides thehydraulic pressure required to operate the hydraulic motor, which motoris controlled by a differential hydraulic pressure regulator that ismechanically coupled to the wind vane. In this fashion the sailboatrudder which is coupled to the hydraulic motor can be controlledrelative to the angle of attack of the wind against the wind vane.

U.S. Pat. No. 4,203,380 discloses a rudder assembly for a boat includinga rudder shaft rotatably mounted to a boat and inclined downwardly andrearwardly. A rudder blade is attached to the lower end of the shaft anda plate is attached to the lower edge of the blade. The inclined shaftpermits control of the rudder assembly from the central portion of theboat while allowing the rudder blade to be disposed near the stern forimproved control. The plate provides for increasing resistance to theflow of water as the rudder blade is moved to the left or right of thestraight-on position.

U.S. Pat. No. 4,327,657 describes a self-steering system to maintain asailing craft on a preselected heading relative to the apparent wind. Anoar member which forms a hydrodynamic servo is mounted on a center bodyfor rotational motion. Also supported on the center body above the oarmember is a wind vane which is mounted for rotational adjustment and forpivotal motion substantially normal to its rotational axis. The centerbody is pivotally supported on the transom of the sailing craft formotion about an axis approximately parallel to the longitudinal centerline of the boat. The wind vane is coupled to the oar member such thatwhen the heading of the sailing craft changes relative to the apparentwind, the wind vane is pivotally driven sidewise by the wind and throughits linkage thereto rotatably drives the oar member. Such rotatablemotion of the oar member from a predetermined neutral position resultsin sidewise water forces thereon which pendulously drive the oar membersidewise and along with it rotate the center body and the vane base. Thecenter body is coupled through a suitable linkage to the steeringcontrol of the sailing craft such that the sidewise pendulous motion ofthe oar causes the steering control to drive the rudder of the sailingcraft in a direction such as to maintain the sailing craft on thepreselected heading relative to apparent wind.

U.S. Pat. No. 4,348,973 relates to a self steering apparatus for a boatcomprising a motion transfer apparatus for converting pivotal movementof a wind vane into rotational movement of a rudder. The latter islocated in a support which is pivotable about the fore and aft axis ofthe boat. A rotatable connection is provided between a control armarranged for movement with the vane and a rudder arm arranged formovement with the rudder, such that, when movement of the vane isinitiated, there is resultant movement of the rudder arm about the foreand aft axis with movement of the rudder about its axis, and subsequentmovement by the water of the rudder support about the fore and aft axis,and movement of the control arm is effected on initial movement of therudder about its axis but does not result from movement of the ruddersupport about the fore and aft axis. Lines transmit movement of therudder support about the fore and aft axis to the main rudder or tillerof the boat.
